  • Patent number: 7313908
    Abstract: A disintegrator apparatus for textile machines is provided that includes a plurality of teeth at a tooth spacing (LZ) of no greater than about 20 mm and preferably less than about 12 mm. The teeth generally include two sections. A first section is located at a tooth apex and exhibits a positive or at least a vertical forward rake (WB). A second section is at an incline, falling in the direction of movement of the operative equipment. The separation distance between the apex of the tooth and a tangential joining point of the vertical tangent creates a transition zone between the first and second sections and forms a technologically effective tooth height (Ht). The ratio of the technologically effective tooth height to the spacing between teeth no greater than about 1.

  • Patent number: 7103440
    Abstract: The invention uses microwaves in the spinning industry in order to determine the band mass of an elongated, substantially non-twisted fiber structure. In addition, a method for measuring the sliver mass from the frequency detuning and the damping of resonance signals of a microwave sensor while taking into consideration the moisture of the fiber structure with a computer is suggested. Likewise, a corresponding spinning preparation machine and a laboratory device for measuring the sliver mass are part of the invention. Lastly, a method and a spinning preparation machine for recognizing foreign matter in a moved fiber structure with the aid of microwaves is suggested.

  • Patent number: 7082746
    Abstract: For the piecing of a yarn in an spinning device, various computation formulas are stored in a control device into which calculated values as well as special data converted into numerical values relating in particular to the fiber material, the yarn and the spinning element are first entered to compute and select settings for operations relevant to the piecing process. A feeding device feeding a fiber sliver to the spinning device is first brought to a high pre-feeding speed by means of such pre-programmed values and converted data. From this pre-feeding speed, the feeding speed is greatly decelerated in steps to its piecing feeding speed in coordination with the release of the yarn to be fed back into the spinning element.

  • Patent number: 7036300
    Abstract: A procedure and apparatus for start-up spinning of a thread in an open-end spinning apparatus is provided. A first and second auxiliary roll-pair are presentable within a thread course during start up spinning. A source of a suction air stream within the spinning apparatus is positioned below the first and second roll-pairs. The source of suction air stream creates a suction flow of air to induce the thread end into the spinning apparatus for start up spinning. A control center is in communication with the first and second roll-pairs, so that the control center controls them. A thread storage unit is positioned between the first and second roll-pairs proximal to the course of the thread. The thread storage unit is in communication with the control center so that the thread storage unit is activated to store and release the thread during start up spinning.

  • Patent number: 6983516
    Abstract: Different improvements of a spinning preparation machine are proposed to measure the fiber sliver thickness or the fiber sliver cross-section of at least one fiber sliver by means of one or several microwave sensors. One improvement is characterized by compressing means and special mechanical guiding elements that can be installed before, after and/or in the microwave sensor. It is also proposed to install a pair of conveyor rollers after a microwave sensor that can be designed in particular as an input roller pair of the subsequent drafting equipment. Furthermore, proposals are made for the calibration of the (at least one) microwave sensor.

  • Patent number: 6834490
    Abstract: In an arrangement for application in open-end rotor spinning, an opening roller is housed in a swivel housing. The swivel housing can, together with the assembled opening roller, be removed from the arrangement for open-end rotor spinning when the machine is in operation. The opening roller, due to its mass, continues to rotate after it has been separated from the tangential belt which drives it. A locking device is provided which prevents the removal of the swivel housing when the opening roller is rotating. This results in the opening roller being at a standstill when the swivel housing is removed. The risk of injury caused by a still rotating opening roller is eliminated.

  • Patent number: 6772697
    Abstract: The invention concerns an arrangement of service positions for maintenance apparatus, which can travel on a guide rail along a multiplicity of similar workstations on a first side of a textile machine, wherein a maintenance apparatus in a first service position at the elevation of a machine framing of the textile machine can be pivoted away from, or transversely withdrawn from the guide rail. Per side of the textile machine, at least two maintenance apparatuses are exclusively assigned thereto, whereby the guide rail on the first side, at least at one end of the textile machine, is elongated beyond the textile machine and a second service position is placed on the elongated guide rail. In this way, it becomes possible, with a large number of workstations to assure the shortest possible duration of a standstill, wherein in the case of a failure or preventive unkeep of one maintenance apparatus, another maintenance apparatus can serve a workstation in a short time.
